Most homeowners never think about their water heater until it stops working. But like any major appliance, water heaters need regular maintenance to perform efficiently and reach their full lifespan. A well-maintained tank water heater can last 12–15 years; a neglected one may fail in 6–8.
Got Plumbing USA connects you with licensed plumbers who perform comprehensive water heater maintenance, including tank flushing, anode rod inspection, pressure relief valve testing, and efficiency optimization.
What Water Heater Maintenance Includes
- Tank flushing — draining the tank to remove sediment that accumulates on the bottom, reducing efficiency and causing noise
- Anode rod inspection — the sacrificial anode rod protects the tank from corrosion. Once it's depleted, the tank itself starts corroding. Replacement costs $100–$250 and adds years of life.
- Pressure relief valve testing — the T&P valve is a critical safety device. Testing confirms it operates properly.
- Thermostat check — verifying temperature settings for safety (120°F recommended) and efficiency
- Visual inspection — checking for leaks, corrosion, proper venting (gas units), and overall condition
- Burner/element inspection — ensuring gas burners fire cleanly or electric elements heat properly
Maintenance Cost
Professional water heater maintenance typically costs $80–$200. Anode rod replacement adds $100–$250 if needed. This is a fraction of the $800–$2,500 cost of premature water heater replacement.
How Often Should You Service Your Water Heater?
Annual maintenance is recommended for all water heaters. If you have hard water (common in the Southwest, Florida, and Texas), flushing every 6 months prevents accelerated sediment buildup.
